11 Claims.

This invention reates to a dispensing apparatus which is adapted to dispense either fuel or compressed air at the will of the operator while at the same time retaining all of the. safeguards against inaccurate measure which are afforded the operator and. the public. More specifically, it relates to a gasoline dispenser which has incorporated in it an air compressor and in which controls are furnished which permit operation of either the gasoline dispenser or the compressor, but not both.

It is an object of the invention to provide a combined fuel and compressed air dispenser which is operated by a single motor.

Another object of the invention is to provide a fuel dispenser and an air compressor with means for selectively actuating one or the other.

Still another object of the invention is to provide means insuring that the fuel dispenser is disabled before the air compressor is activated.

Yet another object of the invention is to provide means for disabling the air compressor before said fuel dispenser is activated.

Still another object of the invention is to provide an interlocked clutching mechanism so that the fuel dispenser cannot be operated until the register thereof is reset.

Yet another object of the invention is to provide a control system whereby the motor switch will be actuated by either the fuel dispenser or air compressor controls.

It is another object of the invention to provide a fuel dispenser and air compressor drive and control system whereby the entire output of the motor may be utilized for either function.

Still another object of the invention is to provide a fuel dispensing and air compressing mechanism in the usual fuel dispenser chassis.

These and other objects will become apparent from a study of this specification and the drawings which are attached hereto and made a part hereof and in which; f

Figure 2 is an enlarged elevation of the apparatus of Figure I viewed from the rear thereof and showing especially the control linkages.

Figure 3 is an elevation of the apparatus of Figure 2 viewed from the left thereof.

Figure 4 is an elevation with parts broken away showing the interlock mechanism.

Figure 5 is a sectional view taken on line 5-5 of Figure 6 showing one of the control clutch as- ,semblles.

Figure 6 is a sectional view taken on the line 6-6 of Figure 5 showing a control clutch.

Figure 7 is a ectional view of the air drier.

Figure 8 is an elevation of an air hose reel and the modified control mechanism utilized therewith.

Figure 9 is a side elevation of the fuel hose hook and control actuator.

Referring now to Figure 1 the numeral I represents the base to which are attached the frame uprights 3, top 5, pump support 1, and meter support 9. An air separator H is supported on I and has attached to it a suction stub I3, a pump I5, an electric motor I! and a discharge pipe IS. The latter is connected through a combined check and relief valve 2| with a meter 23. The discharge pipe 25 connects the meter with the discharge sights 21 which empty into the usual wet hose 29 which terminates in the valved nozzle 31 Meter 23 drives a register 33 which may be of any desired type and which is fitted with a resetting mechanism operated by crank 35. The resetting shaft also actuates the shaft. 31 of the interlock mechanism 39 so that the nozzle support 4| may be actuated after resetting to initiate the dispensing of fuel.

A bracket 43 is attached to members 3 and. supports an air compressor 45 which discharges into an air cleaner 49 through tube 5|. Air passes from the cleaner by way of a T 52, tube 53 to the air hose 55 which is fitted with a chuck 51. A pressure relief valve 41 is provided on the T 52. 7

Reference to Figure 7 will show that the cleaner comprises a tube 59 having a perforated partition 6|. The chamber 62 above the partition being filled with bronze wool 63 or similar material for removing any oil, water or foreign matter which may have become entrained in the air. A cook 65 is provided in the lower chamber 61 to drain off accumulated material.

Referring now to Figures 2 and 3, the motor shaft 69 carries a double grooved pulley H from which power is transmitted to the pump pulley II from which power is transmitted to the pump pulley 13 by a V-belt l5 and to the air compressor pulley .1 by a belt IS. The pulleys l3 and 11 are adapted to rotate freely upon the pump and compressor shafts 8| and 83 respectively and are selectively connected thereto by roller clutches 85 which are identical in construction, and consequently only one is described and shown in Figures 5 and 6. The pulleys are held on their respective shafts by means of a washer and a cotter pin. Y i

Iings "the housing I 55.

between the wall of the notch and thecam.

The plate is notched at I03 to receive the control pawl I05 described below.

Pivotally mounted at I65 on an ear Iiil on the support I is a pawl I99 which is normally urged in a counter-clockwise direction by a spring III, in which it disconnects the pump clutch. A second pawl H3 is pivotally mounted at H5 on a bracket III on the compressor and a spring H9 urges it in a counter-clockwise direction toward engagement with its control plate.

A switch I2I is mounted on a motor and is provided with an operating shaft I 23. Mounted on this shaft for free rotation is a double armed lever I25. A second lever I2? is fixed to the shaft and serves to actuate it to close or open the switch. A rod I29 is connected at its lower end to the pawl I09 and at its upper end to the pawl I13 andintermediate its length it is connected to one arm of lever I25. The other arm of the lever is connected to the rod I3] which is connected at its upper end to the interlock lever I33 (Figure 4) which is actuated by the link I35, bell crank I3! and the hose hook III, subject to control by the interlock mechanism (Figure 9). The connection I39 of rod I29 with link I09 is a simple pivotal connection without any appreciable lost motion, whereas the connection MI between the rod and pawl I I3 is preferably a lost motion connect'ion since the compressor may be stopped with the notch A of the control disc displaced with revSpec't to the pawl.

A bearing bracket I43 extends from the compressor body and supports outboard bearing I45 for shaft 83. .A further extension .I I! of the bracket supports the pivot I I5 of pawl I I3.

The switch lever I2] is connected by -a rod I51 to one end of a yoke I59 which is pinned to rod "I :by pin I54. A rod I55 is screwed in the other end of the yoke and carries a hooked end I5! which enters a slot I59 in the air hose lever I5I, which is pivoted at I55 on the frame. The outer end is formed as a hook 1'65 to support the hose.

The interlock mechanism comprises a reset shaft 55 which has a notched disc I51 fixed to it and a second notched disc I 59 freely rotatable on it. A spring III anchored to each of the discs tends to rotate them relative to each other to separate the notches Il3Il5. Pin 'I'Il in .disc I51 extends through an opening I19 in IE9 and limits this rotation. .A peripheral notch .I8I is .formed in disc I69 and is adapted to be engaged .bypawl I83 on lever I85 pivoted at I86. A dependingarm Iii-I on the pawl :is adapted to be actuated-by a cam I89 mountedat I 91 on the inter- :lockle-ver 433. .A seeker I93 adapted to enter the aligned notches Il3-IFI5 is integral with the cam. The cam and seeker are guided in open- The interlock lever is pivoted on:a frame member at I'9I. "The notches are slightly'wider "than the seeker I93 for a p rpose to be disclosed. n

Operation Assuming that the dispenser is in the inactive condition depicted in Figure l, in which both the air hose and the fuel hose are hung up. The switch is off and the clutch control is in the condition shown in Figure 2. That is, the rod I3I is down and the latch H3 is lifted from its control plate while clutch pawl I09 is positioned in holding relation with notch B of its control plate.

The compressor 45 is clutched to shaft 83 while the pump I5 is declutched from shaft 9|.

Under this condition, if it is desired to use the air service, the air hose is removed from the hook I and the hook is raised or rotated clockwise (Figure 2). This rotates rod I55 and yoke I53 counter-clockwise, pulls up on rod I5I, rotates lever I21 counter-clockwise and starts the motor II.

The motor drives clutch shell 3'! which drives the core 89 by reason of the fact that the rolls have been jammed into the notches 93 by the springs IIII, and the compressor shaft is accordingly driven.

Air is compressed in the pipe 5!, cleaner 49, pipe 53 and hose 55. As the air passes through the cleaner it traverses the wool 63 therein where water, oil and other foreign matter are removed. As these liquids accumulate, they gravitate into chamber 67 where they may be drawn .ofI" through cock 65. The relief valve 41 will blow off air if the pressure in the system becomes excessive.

Rotation of the hose hook 155 in the counterclockwise direction will open the switch.

Should it now be desired to dispense fuel, it is first necessary to operate the reset crank 35. This actuates shaft '31 and discs I59 and 16'! in a counter-clockwise direction (Figure 4) until pawl I83 is received in notch I8I of disc I59. When this occurs the disc I59 stops with notch 1'75 in alignment with seeker I93. Further rotation of the shaft moves disc I67 relative to disc I69 until pin IT! strikes the other end of the opening I59 when it too stops. The notch I13 will then also be aligned with the seeker so that the lever I33 can "be raised by the hose hook 4i, crank I3] and rod I35. I

When this occurs the seeker enters both notches "and cam I 59 rotates lever I to withdraw pawl 183 from notch I8I. Since the notches I'm-I15 are wider than the seeker, the disc I69 will -be rotated slightly by spring III to displace notch 1-8I beyond pawl I83.

Lifting lever I33 also causes lifting of rod I31 which rotates lever I25 counter-clockwise (Figure 2') This pulls rod I29 down and rotates pawl I 1'3 counter-clockwise if the control plate notch A is in the right position, or if it is not, then the pawl will res-t on the periphery of the plate and the lost 'motionconnection will permit the rod I29 to complete its movement to rotate pawl I09 clockwise to free it from notch B.

When this occurs, the control plate of the pump clutch is freed and the pulley I3 is clutched to shaft 8 I.

Simultaneously, the yoke I53 is rotated countier-clockwise about the point I'-5.'I by the upward movement of rod I3I, rod I5I is lifted and, lever 121 is rotated counterclockwise to :close switch I 2|.

The motor starts and the pump is driven. If the pawl I I3 was not seatedin notch A, then the compressor is rotated a partial revolution until the pawl seats and stops the control plate, withdrawing the rolls 99 from the notches 9-3 and declutching the shaft. Thus only the pump will be actuated.

Liquid will be drawn up through suction stub I3, pump I5 and be passed through the air separator II, meter 23, sight glasses 21, hose 29 and nozzle 3I to the receptacle.

When delivery is completed, the operator will push in on the hose hook 4| and hang up the nozzle.

This reverses the rotation of hell crank I31, drops rod I35, rotates lever 533 clockwise and withdraws seeker I93 from the notches II3--Il5 so that spring I II will rotate the discs relative to each other so that the notches are blocked and the reset crank must be again actuated before the hose hook can again be moved.

Rotation of lever I33 also drops rod I3I, rotates lever I25 clockwise which raises rod I29 and sets pawl I09 against the control plate of the pump clutch. The pawl must enter notch B before rod I29 and all the associated parts can move appreciably. Consequently the pump clutch is at once declutched.

This movement of rod I29 moves pawl II3 out of notch A on the compressor clutch and the pulley TI is clutched to shaft 83.

At the same time, the 'rod I55 and yoke I53 are rotated clockwise about point I51, rod I5I is depressed, lever I2! is rotated clockwise and the motor switch is opened to stop the motor.

Thus it will be seen that the air compressor is always conditioned for operation when the fuel dispenser is idle and is deciutched when the fuel dispenser is being used. Conversely, if the fuel dispenser is in use the compressor is declutched so that only one unit will be connected to the motor at a time. The only exception being that both may be connected for a partial revolution when switching from compressor to pumping.

It will also be seen that b reason of the interlocking mechanism and the clutch control system, no fuel can be dispensed unless the register has been reset to zero.

Modified hose handler Instead of hanging the air hose on a hook outside of the housing it may be desired to coil it upon a reel in the space below the pump support 1,

In such a case, as is shown by Figure 8, support means 2i" are mounted on the base I and a reel 263 is mounted on an axle 2&5 held by the supports. A spring 287 is anchored at one end to the supports and at the other on the reel to rotate the reel counterclockwise.

The hose 2% extends through a hole 209 in a guide bracket AI 5, through collar 2 I3 and through an opening N5 in the housing 2I'I so that the chuck 2I3 is within reach of the operator. A spring 22I urges the collar away from bracket 2II while a ball 223 on the hose pulls the collar toward the bracket when the spring 201 rewinds the hose.

A bell crank 225 is pivotally mounted at 221 on the frame and has one arm connected at 229 to the collar while the other arm is connected by means of a rod 233 to a lever 23I which is pivoted at 233 on a clip 235 on the housing. The other end of the lever is connected by a slot 231 to the rod I55 and the remainder of the switch actuating mechanism.

Operation In this modification, as the air hose is withdrawn from the housing, the pressure of ball 223 in collar 2I3 is relieved and spring 22I expands to rotate bell crank 225 clockwise. This pulls down on link 230 and rotates lever 23I clockwise to rotate rod I and the yoke I53 counterclockwise as described above, so as to close switch I2I to start the motor.

If the hose is released, spring 20'! will rotate reel 203 counter-clockwise to take up the hose and when the ball 223 strikes collar 2I3 the parts move reversely to open the switch.

Of course, suitable locking means may be provided to prevent unauthorized access to the hose if desired.

It is obvious that various changes may be made in the form, structure and arrangement of parts without departing from the spirit of the invention. Accordingly, applicant does not desire to be limited to the specific embodiment disclosed herein primarily for purposes of illustration; but instead, he desires protection falling fairly within the scope of the appended claims.
